SAFETY LAMP.

Application led November 18, 1922. Serial No.- 601,768.

.State of Pennsylvania, have invented new and useful Improvements in Safety Lamps, of which 4the following is a full, clear, and exact description.

This invention relates to safety devices primarily designed for use with motor vehicles. l

In driving motor vehicles .at night a great deal of difliculty is experiencedin estimating the distance of one motor vehicle from another. Inability of a driver to locate the left front portion of`an approaching vehicle often results in serious accidents and in some cases the `destruction of life.

The general object of this invention is the provision of a cheap, sim le and e'ricient device for mounting on a ve 'icle to i1lumi nate any portion of it or the ground beneath the said portion of the vehicle in order.

to assist others in determining the location of the vehicle.

A further object of the invention 1s the provision of a safety d evic'e for use with' motor vehicles for signahn toanapproach ing driver the outer line o the vehicle.y

This object is accomplished by providing. a lcylindrical casing of opaque material having an elongated slot in one side for receiving a lens andan opening in one end in which a second lens is mounted, mountino' in thecasing a lam ffor projecting rays olf light through said enses, and 'mounting on the casing means for attachin to any part of the vehicle i'n a horizonta position to illuminate any .portion of the vehicle or the ground beneath that portion, and to throw l a beam of light forward to indicate the locacasing showing the following detailed description and tion of aeparticular portion of the vehicle. These and other objects' of the invention will be more clearly understood from the accompanying drawings. Fi ure l is a perspective view of an automobi e showing the device mounted in position on the front mudV guard of the left side" v Figure 2 is ,a vertical section through 'the construction of the safety device;

Figure 3 is al vertical vcross" sectionuofthe device. Referr .mg 21.in the mu retained in position by means of a nut 22..

ing to the abovejmentioned .draw-1 ings, a motor vehicle 10 is shown with a safety device 11 mounted on its left front mud guard 12. The safety device includes Aa casing consisting of a front section 13,

one end of wh1ch.1s provided wlth an iny ternal thread, and a rear section 14 having lan external thread cut on'one end for engaging 1n the internal thread of the' front section 13. Mounted in the rear section 14 of the casing is a socket 1,5 which makes are standard articles and consequently not set forth in detail. One'oonductor 17 only extends from the source oi'` electricity and connects with the terminal of the socket which does not make electrical contact with the section '14 of the casing: In order` to hold the casing together a clamp `18 Lis mounted thereon at thepoint of juncture. of the'sections 13 andvll.v This clamp is providedwith a stud 19 having a threaded ortion '20 which guard 12,;v This stud is Thus by means of the clamp and stud the. safety device may be attached to the `mnd guard to retain it in auhorizontal position.l

- An elongated opening 23 is cut in the side Yof the front section 13, -of the easing. A lens 24 is mounted in this'opening 23 in alinement with the bulb `16. Another opening 25 is cut'in the forward ,end of the front section 13 of the casing and a lens 26 is mounted in this opening and retained in position by means of la yring 27.l The lens 26 would be so constructed aste focus the raysof light at a short distance in front of .it so as to eliminate `all possibilityof glare which might-l affect approaching drivers. f

The operation of'this safety deviceis as" follows:

'so' (projectsthrough an open-1 It is supplied with current from any suitable source of electric energy through a Vsingle conductor 17. This conductor connects with the terminal of the sockety 115 that is 'not grounded` and current flows# through conductor 17, said terminal of the socket 15, through bulb 16, through the grounded terminal of the socket; 15 and backthrough ground to the sourceof e1ec, tric energy. The lens 24 focuses'the 4lightrays s'o as to illuminate the left front-wheel and the ground fora distance of a foot to the front and to the rear of the Wheel. The light rays passing through the lens 26 are focused a short distance in front of the same and serve as a means for indicating the location of the outer line of the vehicle. llt the driver of the vehicle turns out his left lamp the rays from the safety device can be more easily observed and the location of the vehicle determined with greater certainty.

l would state in conclusion that' While the illustrated example `constitutes a practical embodiment of my invention, ll do not limit myself strictly to the exact details herein ilustrated since manifestly the same can be considerably varied Without departing from the spirit of the invention as defined in the appended claims.

Claims:

1. A device of the character described for use with vehicles, a casing 'formed of two tubular sections having a screw threaded connection with each other, one of the sections having a lens in its end and one side, and the other section having an apertured end,'an electric lamp socket mounted in the other section of the casing With one terminal making electrical contact with the said section, a lamp mounted in the socket and projecting into the section of the casinnesca ing having the lenses, a single conductor leading from the other terminal ot the socket out through the aperture of the end of the section carrying the socket, and means on the casing for securing it to a vehicle.

2. A device of the character described for mounting on vehicles to illuminate the ground beneath particular portions of the vehicle and to indicate the outer lines of the vehicle, comprising a two-section tubular casing, the top section having an elongated slot cut in its Wall and an opening formed in its end, the base section of the casing having a lamp socket mounted therein so that one terminal makes electrical connec- ,tion With the base `sectiomsaid top section being provided with an internal thread While the base section is provided with an external thread for engaging the internal thread of the top section to connect the two sections together, a bulb mounted in said socket, lenses mounted in the openings provided in the top section of the casing tor focusing the rays of li ht trom the bulb, and a clamp encircling t e casing at a point of juncture ot the sections, said clamp being provided with means for attaching it tothe vehicle.
